IMPROVEMENT IN HARROWS.

Specification forming'part of Letters Patent No. 182,736, datedSeptember 26, 1876; application filed March 13, 1876.

To all whom it mag concern:

Be it known that we, EDMUND D. REY- NOLDS and OLIVER BRADFORD REYNoLns,of Brockton, Massachusetts, have invented certain new and usefulImprovements in Harrows, of which the following is a full,,clear, andexact description, reference being had to the accompanying drawings,making a part of this specification, in which Figure 1 is a perspectii eview. Fig. 2 are details to be referred to.

Our invention relates to that class of harrows used for top-dressing;and it consists in the method of securing the teeth to the frame.

To enable others skilled in the art to make and use our invention, wewill proceed to describe the exact manner in which we have carried itout.

In the drawings, A A represent the framework of our harrow, and a, a theteeth,

Itis well understood by those skilled in the practical use of the harrowthat the first rows of teeth striking the rough ground are liable toclog much more so than the teeth which follow them. It therefore becomesimportant to place the points of the teeth of the front rows of a harrowas far apart as possible, and at the same time preserve the properworking character of the implement. To accomplish both these results inthe best manner-that is, to give full distance between the teeth in thefirst two rows, and at the same time avoid dead spacewe have made eachalternate tooth shorter than the other, and bend it into an arc of asmaller circle, thus bringing their points in the same horizontal plane,while their zigzag position greatly increases the distance between them,while they remain in the same radial lines before mentioned.

The shoe 1; is fitted to the frame, with the portion b pendent at rightangles, and perforated to receive the tooth a, as shown in Fig. 3. Thebutt of the tooth a is constructed with an eye, 6, through which passesthe bolt 0, securing both the tooth and'the shoe to the frame A. 7

By this simple and ready means we secure the tooth to the frame, and atthe same time form a brace or bearing to hold it steadily to its work.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

The shoe b, provided with the perforated pendant b, in combination withthe frame A,

tooth on, and bolt 0, substantially as and for the purpose set forth.
